Installing the Rstem package

Hello,

I am trying to install the Rstem package, but I have problems. I am
using Windows XP and the 2.8.1 version of R. I have read the "Add-on
packages" chapter of the "R Installation and Administration" manual,
and also have tried several things, which worked for other people on
the mailing list having faced the same problem
(http://tolstoy.newcastle.edu.au/R/help/06/03/22889.html).

I paste below the things, which I have tried and the results. I don't
understand what the message "installation of package 'Rstem' had
non-zero exit status" mean, which I get on my last try below. Could
anyone advise me what should I do? Thank you.

p.s. I have successfully installed the lsa package, which depends on
the Rstem package.
